He prints out his own test pieces on a 3D printer. Most efficient would be if he sold the output from his printer and then tested it. But if it gets too easy the demand goes up and he won't do it anymore.

Although, how do we know these results are accurate? I didn't go and watch his other videos, but if i recall correctly he'd have to have 400+mph wind in that tunnel to give reliable results for a model that size... it would probably take up his whole garage.

Have you watched enough to understand that the camera is upside down, pointed at an inverted model at the top of a water channel? The stray bubbles shooting downward give it away. This is actually a good match for the Reynolds number.

PS- if we really did want to send him one, I'm sure someone on here would be good enough at scale models to build one for him. We could set up a kickstarter to fund the ~$50 for a model, supplies and time through a few $1-5 donations.

It will cost $50 to package and ship it in one piece. Good price point for a model 3D printed at the point of use though. I already have a 1/25th model I'd like to see him test:
I made it in 1995. It would need the windows filled in.
